Linux Kernel Moves Toward IPv6-Only Future with New Flexibility

This development matters because it enables modular kernel builds optimized for specific network architectures—allowing IPv6-only or IPv4-only configurations tailored to deployment needs. As the internet shifts toward IPv6, this flexibility is crucial for organizations modernizing infrastructure without carrying legacy IPv4 overhead. The patch series marks a pragmatic milestone in evolving the Linux kernel to match the realities of next-generation networking.
